Abstract
The utility model discloses a ball valve convenient to install, detach and maintain. The ball valve comprises a valve body, a ball body and a valve rod. The valve body is formed by a left valve body, a right valve body and a main valve body. The left valve body and the right valve body are arranged on the left side and the right side of the main valve body correspondingly through bolts. Wedge-shaped protruding columns are arranged on the upper side and the lower side of an end face where the left valve body, the right valve body and the main valve body are connected. Wedge-shaped grooves for the wedge-shaped protruding columns on the left valve body and the right valve body to be inserted are arranged on the main valve body correspondingly. The ball body is arranged in the main valve body, a sealing valve seat is arranged between the ball body and the left valve body and between the ball body and the right valve body respectively, the valve rod penetrates the main valve body, the inner end of the valve rod is fixedly connected with the ball body, and a handle is arranged at the outer end of the valve rod. By means of the structure, compared with the existing integrated valve body, the valve body is simple and convenient to install, detach and maintain and can achieve fast maintaining of the valve.
Description
Technical field
The utility model relates to a kind of ball valve.
Background technique
Ball valve is a kind of valve commonly used, its structure mainly comprises valve body, spheroid and valve rod, because the valve body of existing ball valve is generally integral structure, therefore cause the whole loading and unloading of valve and comparatively inconvenience of maintenance, and after assembling is finished, even a certain special position of valve breaks down, also need valve integral body is dismantled, thereby make the maintenance procedures complexity, be unfavorable for quick maintenance.
Summary of the invention
At the deficiencies in the prior art, the utility model provides a kind of ball valve of loading and unloading and keeping in repair be convenient to.
For achieving the above object, the utility model provides a kind of ball valve of loading and unloading and keeping in repair be convenient to, comprise valve body, spheroid, valve rod, described valve body is by a left side, right valve barrel and main valve body constitute, a described left side, right valve barrel is installed on the left and right sides of main valve body by the bolt correspondence, an and left side, the end face that right valve barrel and main valve body join is provided with the wedge shape projection in both sides up and down, and the axial length of described wedge shape projection is 3 ~ 8cm, correspondence is provided with and a described left side on the described main valve body, the wedge-shaped impression that the wedge shape projection plugs on the right valve barrel, described spheroid is installed in the main valve body, and described spheroid and a left side, all be equiped with seal valve seat between the right valve barrel, described valve rod is arranged in the main valve body, and the inner and the spheroid of valve rod are affixed, are equiped with handle on the outer end of valve rod.
The beneficial effects of the utility model are: adopt said structure, because the valve body that the utility model adopts is to be assembled by left and right valve body and main valve body to form, therefore compare existing integral type valve body, valve body dismounting provided by the utility model is more easy, and during maintenance, also need not the valve integral demounting, just only need the dismounting left valve barrel when this part breaks down when left valve barrel, just only need the dismounting right valve barrel when this part breaks down when right valve barrel, thereby simplified maintenance procedures, save engineering time widely, can realize the quick maintenance of valve.
The utility model can further be set to all clamp gasket seal between described main valve body and the left and right valve body, and the thickness of described gasket seal is 3 ~ 5cm.
The utility model also can further be set to be provided with between described valve rod and the main valve body stem packing and Gland.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Provided a kind of ball valve of loading and unloading and keeping in repair be convenient to as shown in Figure 1, comprise valve body 1, spheroid 2, valve rod 3, described valve body 1 is by left valve barrel 11, right valve barrel 12 and main valve body 13 constitute, described left valve barrel 11, right valve barrel 12 is installed on the left and right sides of main valve body 13 by bolt 4 correspondences, and left valve barrel 11, right valve barrel 12 is provided with wedge shape projection 14 in both sides up and down with the end face that main valve body 13 joins, and the axial length of described wedge shape projection 14 is 3 ~ 8cm, the corresponding wedge-shaped impression 131 that plugs with described wedge shape projection 14 that is provided with on the described main valve body 13, during assembling, can pass through described left valve barrel 11 earlier, wedge shape projection 14 on the right valve barrel 12 is plugged in the corresponding wedge-shaped impression 131 of described main valve body 13 and positions, again by bolt 4 with left valve barrel 11, right valve barrel 12 lockings install on the main valve body 13.Described spheroid 2 is installed in the main valve body 13, and all be equiped with seal valve seat 5 between described spheroid 2 and left valve barrel 11, the right valve barrel 12, described valve rod 3 is arranged in the main valve body 13, and the inner of valve rod 3 and spheroid 2 are affixed, are equiped with handle 6 on the outer end of valve rod 3.All clamped gasket seal 7 between described main valve body 13 and left valve barrel 11, the right valve barrel 12, and the thickness of described gasket seal 7 is 3 ~ 5cm.Be provided with stem packing 8 and Gland 9 between described valve rod 3 and the main valve body 13.
Adopt said structure, because the valve body 1 that the utility model adopts is to be assembled by left valve barrel 11, right valve barrel 12 and main valve body 13 to form, therefore compare existing integral type valve body, valve body 1 dismounting provided by the utility model is more easy, and during maintenance, also need not the valve integral demounting, just only need a dismounting left valve barrel 11 when this part breaks down when left valve barrel 11, just only need a dismounting right valve barrel 12 when this part breaks down when right valve barrel 12, thereby simplified maintenance procedures, save engineering time widely, can realize the quick maintenance of valve.
